FALSE SIGNALS
1. TRASH:
The most common source of false signals.
Large or irregular pieces of trash may give positive,
lock-on false signals. In this case you’ll usually have
to dig the target, but with experience you’ll be able
to eliminate many of the large targets whose size
will be obvious when you go into the pinpoint
mode.
Another false signal response may be a “one-
way” or disappearing signal. You’ll sweep over the
target and get a good signal but nothing on the
return sweep. When this happens you’re over a
target that the CZ-5 can’t positively identify due to
its size, shape, depth or alloy. The CZ-5 may ID it as
a coin when swept from one direction and iron on
the return sweep. If your DISC control is set at “0”
you’ll hear first a high tone (coin) and then a low
tone (iron). Or if your DISC control is set higher, to
reject iron, you’ll hear the high tone sweeping one
way and nothing the other way.
Quite often the signal will just disappear and
you won’t be able to find it no matter which
direction you sweep. These one-way and
disappearing signals are usually trash and as a
general rule you should ignore them. If you have
any doubts, press the PINPOINT button to get an
accurate location and then ID the target. If you
get a good repeatable, lock-on ID, dig it. If you
still get a one-way signal or it disappears, move
on. Also, if your pinpointing location is different than
your ID location, your target is probably a piece of
iron.
Reducing your sensitivity level or increasing the
discrimination level may reduce the number of
false signals caused by trash.
2. DEEP TARGETS:
Deep targets, just barely within the
range of the CZ-5 may be misidentified. For
example, a deep coin may ID as iron or a deep
piece of iron may ID as a coin. There’s not much
you can do to avoid this other than to use your
